Petsmart is having a 30% sale on Clear for Life acrylic tanks and I think I'm going to get a 125 gallon.

Are Clear for Life tanks good?

They have plain 125 tanks at 6', $670 or tanks that have a built-in filtration system and a painted back that are 5' wide, $1170 with discount and store pickup. Either way I'm going to be using a FX-6 but was wondering if it was worth getting the extra filtration. What do you think?
